To ali 207mm 'it ma-fz/ con'ce'r'n:

Be i known that I, ARTHUR R. BECK, a citizen of'A the United States,land av resi'dent of Siou'X City, in theicounty of lVoo'dbury I andState of Iowa, have invented Getta-in new and useful Improvem'ents inOil Cans, of which the following is a specific?ation.l

My inveh'tion rel'ates to' that classI of oil cans in which the 'oil isprojected 'from 'a spout vunderV po'sitiv'e pressure from a force pump.

An object of my invention is to provide anv oil can of this 'class ofsimple, durab'le and inexpenslive construction.

vMore spe'cific'aflly it is my object 'to prvide an oil can of thisclass in which .ah induction tube, supported bn a removable cap, extendsinto the oil can body,- has at its lower end an inwardly-openingcheckvalve, and at its upper' end an outwa'rdlyopening check-valve, aspout attached' to its upper end, and a pumpl mechanismcommunicatingwith it. o

A further vobject is to provide an" improved valve mechanis'm of simple,durable and inexp'ensive construction, so arranged that the two valvesare readily. and easily accessible andre'movable', the valves beingidenti'calv in structure. g A

`More specifically, re'f'rring to the last object, it' isl niy object toprovide an oill can. as' ln'en'tioned inl which the upper valve issecnred, in place by the: spoin, Vwhich is' removable, 'and in which thelower valve sec'ured in place by an apertured cap', the valves being'engaged between the respective spout and cap and the induction tube.

A: further object is t`o provide anl oil can as described including thecan body, v the remqv'able cap, the inducti'n' tube, valves, spout andpnm-pi-ng' niechansm, and also handle pernianently fi'x'ed to the 'capinfix'ed relation to the puinpng mechanisni, and having a pcrtion freelyencii'cling thecan body, for bracing the lower end of the l'iandle,where'by the handl'e and' pump may maint-in theii proper relation toeach other during the rer'n'm'al and' replacing of the can body inengagement with the cap;

vWith these and other objects view, my in'ven'tion consists in theconstruction, arrahgemen'tand combination of the various ptr'ts of mydevice, where'by the objects Fi'g. 4 shows an' enlarged detailpers'p'ective view of one of the valves.

Referring to the accompanying drawin'gs', I have used the referencenmeral 10 to indicatev generally an oil can body. which is preferably ofstandard construction. The can body, 10, has a n'eck, 11', whichispreferahly threadd to receive' the cap', 12. It will be undrstood,however, that other means of connecting the cap and can body might beemployed, as for instance,'inclined lugs formedv on 'the Cap, 12, rneck, 11, and co-operating with register-i'ng in'clined grobves inv theco-acting element.

A gaskt; 12,l adheingfto the extending under edge of the top, 13, isused to seal' the jun'cture between the cap, 12, and neck, 11.

Thecap; 12', has the upper wa11,.1 3. An in'duction tube-, .14, isprovided which entends through the cap,l` 12, and is soldercd orotherwisev suitably secur'ed to the b'ottom wall, 12, thereof. Theuppei' end of the induction tube, 14', is extended through' the wall,13, and thence enlarged to form a valve `ch'amber, 1j5. The ch'ainber,15, thus is provided 'atits lower extre'm'ity with a shou'lder, 16,formed by the enlargement of the tube, 14.

The spout, 18, has a threaded base portion, 19, adapted to be receivedin the Chamber, 15, an'dv having at its lower edge an inturned fiange,20, which engages' the valve bo'dy, 17, and secures it against theshoulder, 16 of'the valve Chamber, 15, when the spo'ut is threaided intoplace. The lower end of the induction. tube, 14, is provided with' theinturned flange or shoulder, 21,, against which the valve body, 17, ofthe lower valve is seured by means of the -lpertured cap,

22, threaded onto the enlarged end, 23, of the induction tube, 14.

Each valve comprises a. valve body, 17, a valve proper, 24, having anopening, 25, at one side, a slot, 26, in the other side, and a U-shapedrod, 27, secured at its ends into the valve body, 17, and having itsarms eX- tended through the opening, 25, and the slot, 26.

It will be seen that a simple construction is thus provided by which thevalves may be readily removed for replacement or repair, and in whichthe valves are identical in construction. Cheapness and simplicity, aswell as the advantage of accessibility, are thus obtained.

A pump cylinder, 28, communicates with and is secured to the upper endof the induction tube, 14, and is closed at its outer end with anapertured cap, 29. A piston rod, 30, extends through the aperture of thecap, 29, being slidably mounted therein, and receives at its end thedouble-acting piston, 31. The outer end of the piston rod, 30, ispreferably provided with a thumb-engaging loop, 32.

It Will be understood that as the piston, 31, is moved outwardly thecheck-valve in the upper end of the induction tube will remain closedand oil will be drawn through the lower valve. As the piston is movedinwardly the lower valve will close and the upper valve will be forcedopen to allow the oil to be forced up through the spout.

A Very important feature of my invention resides in the handleconstruction, which I will now describe.

In any oil can in which a pump is employed, it is desirable that thehandle by which the oil can is carried be situated in a position fromwhich the plunger or actuated member of the pump may be convenientlyreached by the thumb of the hand which grasps the handle, in order thatthe oil can may be manipulated entirely by one hand. This has beenarrived at in some devices by providing co-acting devices on the canbody and cap which serve to bring the can body and cap intopredetermined relative positions when they are engaged with each other.By such means the handle may be attached to the can body in the properposition and relied upon to always maintain its correct positionrelative to the pumping mechanism. However, such clevices have notprovenentirely practical, being often too complicated and alsointerfering with the registering of the cap and can body in such tightfit as to form an oil-tight `oint.

J The term pump is used in the claims to include the pump cylinder,piston i and actuating piston rod.

In other constructions, the neck of the oil can is rotatably attached tothe can body,

so that the cap may be threaded down to close engagement with the neck,and the neck and cap both then rotated to position to properly align thepump and handle. It will be seen that in each of these constructions amore complicated structure is involved than is present in applicanflsinvention, and the standard can body is not utilized.

It is much preferable to e'inploy a standard can body construction, suchas illustrated herein, having a screw threaded neck into which the capmay be screwed, and between the upper edge of which and the flange, 12a,of the cap a tight joint may be secured by screwing the cap downsecurely. the cap in attaching it to the can body, it will be diificultto bring it to the same position relative to the can body each timethatit is threaded into place, and still have it screwed tight againstthe neck. The ordinary wear in the gasket, which is ordinarily usedbetween the cap and can neck to make an oil-tight joint, as well as theresiliency of the metal wall in which the It will be seen that in sorotating threads are formed, will allow variations in i the amount ofsuch relative rotation of the cap and can body.

I therefore provide a handle formed of a single piece of Wire rod, bentat its central portion to form a ring, 34, which normally encircles thecan body, 10, the two ends of the rod being thence extended away fromthe ring, 34, in the plane thereof, thence bent upwardly to form thehandle proper, 33, thence bent back in a plane substantially paralleltothat of the ring, 34, spread apart to encircle the cylinder, 28, andvalvechamber, 15, and soldered or otherwise suitably secured to theupper wall, 13, of the cap, 12.

It will be seen that the handle is thus secured and permanently fixed tothe cap, 12, and freely encircles the can body when the same is inplace. The ring 34;, serves to brace the lowerend of the handle againstthe can body, and also to help guide the can body into position toregister with the cap when being inserted thereon. The can body may thenbe rotated until a tight engagement is secured with the cap and thehandle will remain continuously in the correct position relative to thepiston rod, 30.

The advantages of my improved construction are several. The valves areinterchangeable and may be replaced with little trouble. The spout isquickly replaceable, and also serves to hold the upper valve inposition. The ordinary can body may be used, thus increasing the utilityof the rest of the device, which may be used with the bodies of otheroil cans. It is thus possible to replace the can body from many sourcesshould it become impaired. When the can is screwed into place on thecap, the handle,

llO

33, may be used as a lever in obtaining a close engageme'nt. The handleconstruction is very cheap, and the arrangement of the handle and the'thumb-engaging loop, 32, make it very convenient for the operator touse the oil can. The use of the thumbengaging loop, 32, eliminateslSprings commonly used in oil can pumps, and eliminates the obje'c-tionof the rod, 30, continuously remaining in extended position when not inuse.

Some changes may be made in the construction and arrangement of theparts of my invention without departing from the real spirit and purposeof my invention, and it is my intention to cover by my claims anymodified forms of structure or use of mechanical equivalents which maybe reasonably included within their scope.
